SLAC-PUB-8466The Silicon Tracker of the Beam Test Engineering Model of the GLAST Large Area Telescope

Abstract

The silicon tracker for the engineering model of the GLAST Large Area Telescope(LAT) has at least two unique features: it employs self triggering readout electronics, dissipating less than 200 mu-W per channel and to date represents the largest surface of silicon microstrip detectors assembled in a tracker (2.7 m2). It demonstrates the feasibility of employing this technology for satellite based experiments, in which low power consumption, large effective areas and high reliability are required. This note describes the construction of this silicon tracker, which was installed in a beam test of positrons, hadrons and tagged photons at SLAC in December of 1999 and January of 2000.

Notes

The PDF version of this document was distilled from a
PostScript file most likely created from LaTeX source which
used Type 3 fonts. The resultant PDF may be unreadable
on the screen at the default viewing magnification
(fonts will appear bitmapped, jagged), though the type will
be legible at higher magnifications.

Despite the cosmetic problems resulting from the
use Type 3 fonts in the original source file, such PDF files print
without problems; likewise, the onscreen text is searchable and
selectable.
